[hibernate-dev] add a critically important notice to documentaion in Search

[Sanne Grinovero]

Hi Hardy,
it seems we failed to properly warn users to use the new Solr packages
you prepared [1];
I was going to open an issue for this to hopefully have it included in
the release, but it seems
I'm too late to mark it for the release of monday.
Could you please reopen and add a warning in the docs before releasing it?
I hope it's possible as it seems quite critical, otherwise please
mention it in the release
announcement.

Thanks!

Sanne
